Last Sunday is my classmate Mary's brithday.We went to your restaurant so as to celebrated Mary's brithday.But your restaurant was not good than I expected.We couldn't tolerate that restaurant at all.The service was really bad and the food was awful.The most unbearable was the hygiene of the restaurant was horrible,we felt very disgusting.
We complained about the food , the hygiene and the the service to the waiter.But his attitude was very pride and he ignored us.It was really provoking! Finall

一个很简单的方法就是先写一篇中文的，然后翻译成英文的，就这么简单，呵呵。。。。
